      I live in the Santa Cruz area where Hemp is pushed upon everyone like it's the greatest thing in the world for food, clothing, oils, etc. etc., but along the way they'd like you to forget their real agenda is to legalize pot. So with that in mind, I bet some locals could find a way to power a Laptop off Hemp, or even pot to show it has more benefits and should be legalized, and so on.

    I read about spinach power a few months back, took me a few minutes to believe it wasn't a hoax, but it isn't. Basically plant proteins are the original solar cells but haven't been usefully harnessed for electrical power generation. Now e're getting close:

    • US researchers have made electrical cells that are powered by plant proteins.

      The biologically based solar cells, which convert light into electrical energy, should be efficient and cheap to manufacture, says co-creator Marc Baldo of the Massachusetts Institute of Technology...

      Baldo's team isolated a variety of photosynthetic proteins from spinach and sandwiched them between two layers of conducting material. When light was shone on to the tiny cell, an electrical current was generated...

      The prototype cells still need a little refinement. At present, they can generate current for up to 21 days; then they give up. So alternatives that last longer are needed.

      The cells also convert only about 12% of the absorbed light energy into electricity. Still, the researchers believe that it should be possible to reach 20% efficiency, which is better than typical values for commercial silicon solar cells.


    Full here
    It may be that more efficient and more durable chloroplasts can be found or made. The evolution of solar power seems to be going in several directions at once. It makes me wonder what experiments are in progress and not reported yet?

    It's possible to make *any* achievement sound trivial by choosing the right words. You call this "using Spinach to power your cell phone" because you're just reading the summary.

    Consider that conventional solar cells are among the most toxic devices now made and you've got a new way to avoid dumping horrible chemicals into the environment, a sustainable way to have solar power, and spin-offs of the knowledge to more efficiently reclamate CO2 pollutiona t the production site. How does "the survival of humans on earth" stack up to "ending homelessness"?

    Of course, the ways to end homelessness in the long run are drug treatment, education, and job creation. New kinds of cell-phones, and hence more jobs, are the main place you'd use engineers and organic chemists to fix homelessness.

  23. Efficiency by the+JoshMeister · · Score: 3, Interesting


    My first instinct was, "Wait a minute... they want to add a third wheel to solar energy?" We already have silicon solar panels that convert sunlight into energy. So why add something in between? Wouldn't that be less efficient?

    The more I researched, though, the more I realized that my initial reaction was somewhat rash. Think about it: if nature already has a time-proven method, why not harness that rather than reinventing the wheel? Especially if the "reinvented" (silicon) method is less efficient.

    I found a CNN article from 2 October 2003 where this idea was explained. Back then, less than a year ago, it was estimated that the efficiency would reach 10 percent by the end of 2004. According to one source referenced by another poster, we're already at 12 percent, and now achieving 20 percent is expected! (According to the CNN article, 20 percent is the efficiency of our current silicon solar power.) If the technology continues to develop at this rate, it could become more energy-efficient than silicon and allow for some very cool technology in the not-too-distant future.

    (What exactly that technology might be, I'm not too sure. Who wants a disposable cell phone battery when current ones can be recharged in a couple hours? Anyone have any thoughts on how this tech could be best used?)

    I used to work in the ag-packaging industry.

    Boxes for spinach are very distinctive, because they have a TON of holes in them to allow cooling systems to be more efficient when they're stacked on a pallet in a refrigerated truck etc.
    (most boxes for leafy greens-lettuce, etc. have a few holes but nothing like on the scale of spinach boxes)
    When I asked about this, I was told that the spinach is so biologically active--even after being picked--that it generated enough heat inside the boxes to require extra cooling--otherwise the shelf life would plummet.

    Hint: keep your greens at EXACTLY 34F / 1C (no lower than that, and not much more than a couple of degrees higher). They'll last far, far longer in your refrigerator!

    So, I guess that's why they picked spinach for this project. That dark, dark green is there for a reason.
